Claims. (Cl. z11-90 The present invention relates to perforated support board attachments and particularly to such attachments which are removably secured to the perforated support board.

The primary object of the invention is to provide a shelf attachment for perforated support boards in which the shelf is positively retained in supporting position.

Another object of the invention is to provide resilient means for securing perforated support board attachments in attached position on the support board. 7 i

A further object of the invention is to provide an inexpensive attachment for perforated support boards which will positively secure articles to the support board in suspended position thereon.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings, in which:

Figure l is a perspective view of theinvention'shown partially broken away for convenience of illustration;

Figure 2 is an enlarged fragmentary*vertical sectional view taken along the line 22 of Figure 1; looking in the direction ofthe arrows; 7 7 I Figure 3 is a perspective view. of one of the shelf support members;

Figure 4 is a fragmentary perspective view of the shelf attached to one of the support members in inverted position;

Figure 5 is an enlarged fragmentary perspective view of the rear edge of one end of the shelf;

Figure 6 is a perspective view of a central support for the shelf;

Figure 7 is a perspective view of a modified form of shelf support.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally a support board having a plurality of perforations 11 formed therein. The perforations 11 are arranged in equispaced horizontal and vertical rows and are adapted to have attachments fitted thereto.

A shelf attachment, generally indicated at 12, is mounted on the perforated support board 10 and includes a pair of opposite end supports 13, 14, a shelf panel 15 and in some instances may include a center support 16. The opposite end supports 13, 14 each include a horizontal base rod 17 having an offset hook 18 formed on each end thereof for engagement through the perforations 11 in the perforated support board 10. An upright rod H depends perpendicularly from the base rod 17 for engagement with the face of the support board 10.

A generally horizontal shelf support rod 20 is integrally formed on the lower end of the upright rod 19 and is perpendicularly offset therefrom to extend generally perpendicularly outwardly from the perforated support board 10. A barrier rod 21 is provided with an upwardly offset inner end portion 22 which is secured in depending relation to one end of the base rod 17. The barrier rod 21 extends outwardly from the support board 10 adjacent to Stes Pa e the shelf support rod 20. 'The barrier rod 21 slopes downwardly and outwardly and has its outer end in horizontal alignment with the outer end of the shelf support rod 20. f A relatively short transverse rod 23 extends horizontally between and integrally connects the outer ends of the shelf support rod 20 and the barrier rod'21, as can be clearly seen in Figure 3.

e The shelf 15 is a generally rectangular panel and includes a pair of perpendicularly o-fiset flanges 24, 25 on the outer and inner longitudinal edgesrespectively of the shelf panel 15. While the flanges 24, 25 have been illustrated as extending in the same direction'from the shelf panel 15, it should be understood that these flanges 24,

25 may extend oppositely from the shelf panel 15, if such be desired.

The shelf panel 15- and the flange 25 have a vertically extending notch 26 formed therein adjacent the opposite ends of the shelf panel 15. The notch 26 extends through the rear edge of the shelf panel 15, as can be clearly seen in Figure 5. A post 27 provided with heads 28 on its opposite ends extends loosely through a bore 29 in the shelf panel 15 adjacent the flange 24 and adjacent the opposite ends of the shelf panel 15.

The shelfattachment 12 is secured to the perforated support board 10 by mounting the oppositely formed support members 13, 14,-as illustrated in Figure 1, in horizontally spaced apart relation. The shelf panel 15 is supported on the shelf support rods 20 with the barrier rods 21-forming a guard at each end of the shelf panel- 15 to prevent merchandise from being displaced therefrom. The notches 26 in the panel 15 and flange 25 permit the flange 25 -to engage around the rod 19 and around the shelf support rod 21) so that the flange 25 closely engages the forward face of the support board 10. With the panel 15 supported on the shelf support rods 20, the post 27 engages behind the transverse rod 23 locking the shelf panel 15 against outward sliding movement thereon.

The shelf panel 15 may be inverted when desired so as to have the flanges 24, 25 extending upwardly and in this position the headed post 27 loosely engaged through the bore 29 falls by gravity to a depending position to engage the transverse rod 23 in the same manner as described above.

Referring now to Figure 6, a center support 16 for the shelf 15 is illustrated. The shelf support 16 is shown in dotted lines in Figure 1, illustrating the application thereof to the shelf panel 15. The center support 16 includes a generally upright base rod 30 which extends perpendicularly and has a shelf support rod 31 extending perpendicularly outwardly from the upper end thereof in generally horizontal relation. The shelf support rod 31 has a downwardly offset inner end portion 32 which is welded to the upper end portion of the base rod 30 and carries an offset hook 33 integrally formed thereon for engagement with the perforations 11 in the support board 10. A brace rod 34 has its outer end integrally connected to the outer end of the shelf support rod 31 and slopes downwardly and inwardly therefrom and is connected to the lower end of the'base rod 30 by welding. An offset hook 35 is integrally formed on the inner end of the brace rod 34 in vertically spaced relation to the ofli'set hook 33 for engagement with the perforations 11 in the support board 10. The base rod 30 is provided with a horizontally extending latch rod 36 for latching engagement with a spring latch 37. The spring latch 37 is a flat plate having integral hinge barrels 38 pivotally encompassing the base rod 30 on opposite sides of the latch rod 36. A pair of oppositely disposed arcuate spring fingers 39 are formed onone end of the latch 37 and the latch rod 36 is adapted to resiliently and releasably engage therebetween to latch the center shelf support 16 in perpendicular relation to the support board 10. The

offset hook 33 is somewhat longer than the offset hook 35 .to permit the flange 25 of the shelf panel 15 to engage between the inner end of the shelf support rod 31 and the support board 10.

A modified shelf support, indicated generally at 40 in Figure 7, is provided for supporting the opposite ends of the shelf panel 15 from completely beneath the shelf panel 15, omitting the barrier rods 21 used in the shelf supports 13, 14-. The shelf support 46 includes a generally horizontal base rod 41 having offset hooks 4 2 inte grally formed on opposite ends thereof. A shelf support rod 43 is provided with an inwardly and downwardly sloping offset inner end portion 44, integrally formed thereon. An upright rod 45 is integrally formed on the inner end of the ofiset portion 44- and extends downwardly therefrom in vertical relation with respect to the base rod 41. The upright rod 45 and the inwardly offset portion 44 of the shelf support rod 43 are secured to the center of the base rod 41 at their apex by welding. An upwardly and outwardly sloping brace rod 46 is integrally offset from the lower end of the upright rod 45 and extends to the outer end portion of the shelf support rod 43 and is welded thereto at 47. A horizontal eye 48 is integrally formed on the outer end of the shelf support rod 43 to cooperatively receive the headed post 27 of the shelf panel 15. The downwardly sloping offset inner end portion 44 of the shelf support rod 43 provides a support for the shelf support rod 43 sufficiently above the plane of the base rod 41 so that the flange 25 of the shelf panel 15 will clear the offset hooks 42 and so that the shelf support 40 can be swung on its offset hooks 42. when removing it from the support board 10.

Having thus described the preferred embodiments of the invention, it should be understood that numerous struc tural modifications and adaptations in addition to those illustrated may be resorted to without departing from the scope of the appended claims.
